Links/Bookmarks April 2017

Every once in a while I dump the links that land in my bookmarks. I find these links mostly through HN or Reddit, or somewhere else on the web.

My focus is mostly on "fun things", from web-development tools, machine learning to ethereum. Those are the areas of interest for me. The tools are handpicked, of course, what else.

Here are the links I found interesting since February 2017:
